4.3.12. ExternalSurface operator

The ExternalSurface operator takes the input mesh and calculates its external faces and outputs polygonal data. The ExternalSurface operator is not enabled by default but it can be turned on in the Plugin Manager Window. The ExternalSurface operator can be useful when creating plots that only involve the external geometry of a plot - such as when you create a Vector plot of surface normals.
